EIN'AR PEDERSEN, OF COPENHAGEN, DENMARK.

HAIR-PIN.

Specification of Letters Patent.

Patented July 8, 1919.

Application filed April 12, 1918. Serial No. 228,162.

To (all whom. it may concern:

Be it known that I, EINAR PEDERSEN, of Copenhagen, Denmark, residing atNo. 51 Gammel Kongevej, have invented certain new and usefulImprovements in Hair-Pins, of which the following is a specification.

My invention concerns a hairpin, the special form of which prevents itfrom dropping out.

For the secure fastening of the hairpin various other forms of the legsof the hairpin have formerly been proposed.

The disadvantages of the hairpins, known hitherto, are that they arerather expensive to make, and they are very apt to dishevel the hair.

Whereas the present invention concerns a special form of the legs, bywhich the pin, after having been put in, will be unable to drop out. Theadvantages of the present invention are that the making of the pin isnot more expensive than that of the usual straight ones, and it will notdishevel the hair.

The invention is shown on the drawing representing a hairpin seen fromthe side.

On the drawing the legs of the pin are marked 1 and 2.

The characteristic feature of the invention consists in both legs beingcurved; but in order to attain the legs preventing each other fromdisplacing through a movement of the hair, the two legs are curved withdif ferent radii of curvature.

Itfor instance leg 1 begins slipping, leg 2, being curved according to acurve having a lesser radius of curvature, will oppose this movement ofleg 1, and vice-versa leg 1 will oppose any movement of leg 2.

Having now described my invention what I claim is new and desire tosecure by Letters Patent is:

A hairpin comprising a single smooth piece of material, having a bightand two legs, said legs lying in a common plane and being of difierentcurvatures.

In testimony whereof I my signature in presence of two witnesses.
